Calibration
Remote Interface Calibration Procedure
190 Operating Manual for XDC Series Power Supply
3. Enter voltage data
Enter the voltage at the current programming lines, read from the external DVM.
CAL:ANAL:5V:PROG:CURR:DATA <voltage>
4. Maximum calibration level
Set the input to the programming lines to approximately 4.5V (90% of full
scale).
Set the power supply to receive 5V analog current programming calibration data
by sending the command:
CAL:ANAL:5V:PROG:CURR:LEV MAX
5. Enter voltage data
Enter the voltage at the current programming lines, read from the external DVM.
CAL:ANAL:5V:PROG:CURR:DATA <voltage>
6. Power supply calculates and stores calibration constants.
Analog Programming Interface Current Readback Calibration
1. Attach a DVM across the current readback lines, Pins B6 and B1(GND).
2. Minimum calibration level
Set the current readback lines to approximately 10% of full scale by sending the
command:
CAL:ANAL:5V:READ:CURR:LEV MIN
3. Enter voltage data
Enter the voltage across the current readback lines, read from the external DVM.
CAL:ANAL:5V:READ:CURR:DATA <voltage>
4. Maximum calibration level
Set the current readback lines to approximately 90% of full scale by sending the
command:
CAL:ANAL:5V:READ:CURR:LEV MAX
5. Enter voltage data
Enter the voltage across the current readback lines, read from the external DVM.
CAL:ANAL:5V:READ:CURR:DATA <voltage>
6. Power supply calculates and stores calibration constants.
